// parseFloat takes in a string value and converts it to a float 
// The parseFloat function will look at the first character of
// the string and decided whether that character is a number or not
// If not the parseFloat function will return Nan

let stringNumber = "8.0"

let floatNuumber = parseFloat(stringNumber);

//This converts your variable to a float

var num = 3
parseFloat(num);

parseFloat("4").toFixed(2)
